Attorney filed false information to the court

How do I bring this issue of the attorney, and the defendants, filing false information to the court and presenting it as evidence in a hearing? I can prove that the evidence is false. I do not know if this is deemed perjury, fraud, or is considered an act of contempt. I am a pro se plaintiff, and the Defendants have obtained counsel. there have been approximately three hearings where they have filed, submitted, and brought before the judge false evidence. Thank you
